For example I want to report a bug to Team17: I need to search when the part that I want happens and say to people start from that time (X minutes). Or if i want to upload a trick for WKB: I need to do the trick again in the beginning of a new match and quit the match to do a short replay with only the trick, without unnecessery parts and with a light file.

This takes more time and patience to do. Extracting a replay part as a small replay would be much more easier to show to people the part you wanted, they would just double click the replay and would appear only the trick or bug part. To extract the part from the replay it would be easy: right click on the replay, click "extract replay part at..." and then you put the time of the beginning of the part and the time of the end of the part. A light replay file would be extracted with the trick/bug only.

In the same way now you can record an off-line game with comments in the chat box, what if we could add comments to an existing replay file? comments that could be displayed in the chat box as you watch the replay. If it is not something hard to do please consider it, as it'd be extremely useful to teach the strategical side of the game.
Who wouldn't like to watch a replay of a final after the players added the comments of what they were thinking during each turn?. Moreover, experienced players could check replays of not so experienced ones and comment on them, pointing out mistakes and what could have been done instead.

In case some schemes, this could be handy, because it would remember not only the victories so far, but the collected crates and used weapons as well.

Adding a button for this would likely to be problematic, so it could be done using a chat command like "/save" which would save the match using a default name - ie. timestamp, players, etc. - or "/save filename" to name it something else.

The saved match would contain:
- The scheme file - this might be no problem at all.
- The players' names - this could be done by a list, or something, only saving the actual players, allowing spectators to join in mid-game or not to be required to join in order to continue the match. The player colors and joining order shouldn't matter. Also, it would be easier for players if this would be saved in a readable form, so if someone changed his/her nickname, it can be changed back to fit.
- The number of teams a player has - this could allow a player to continue a game with a different team, using a different color. In case of the players being listed like the example above, this info should go after each player in a numerical format, assigning a different number to each differently colored team, and storing these numbers after the players' list. This system would allow players to have more than one team of the same or different color, or allied teams.
- The list of weaponry each different colored team (or alliance) has - this could be saved, again, in a format similar to the scheme format, or as a simple list of weapons and how many does a team have. Either way, here, the scheme's setting of stockpile should be taken into consideration during loading, whether to fill up every weapon that the scheme provides and take away the others (-> no stockpile), to add the default weapons to the accumulated ones (-> stockpile) or to do nothing (-> antistockpile).
- The number of victories each team or alliance has.

To load a match, a command such as "/load filename" should be used, and a succesful loading should switch the users to the post-game/next-game lobby with each of the teams having their victory count set, and the weaponry information loaded to wherever that information is stored between games.

In case of something not going as the saved match would "except", an error message should be displayed in the form of a chat line. These errors messages should contain, in case of what went wrong, that:
- The saved match's file is corrupted.
- One or more players are missing - here, the possibility of someone's nickname not being the same as it was during the last time should be noted, as well as which player is missing.
- One or more teams are missing - since the loading would match the teams with the players, this could display who's team is missing too.

And that's probably it, I hope I provided as much details and ideas as possible. :)
